A ConfigMap is an API object used to store non-confidential data in key-value pairs. Pods can consume ConfigMaps as environment variables, command-line arguments, or as configuration files in a volume.What is the difference between ConfigMaps and Secrets in Kubernetes ConfigMaps are used to store non-sensitive configuration data, such as environment variables or configuration files. Secrets, on the other hand, are designed for storing sensitive information like passwords, API keys, or TLS certificates.A ConfigMap is not designed to hold large chunks of data. The data stored in a ConfigMap cannot exceed 1 MiB. If you need to store settings that are larger than this limit, you may want to consider mounting a volume or use a separate database or file service.
Where is ConfigMap stored in Kubernetes : Kubernetes stores API objects like ConfigMaps and Secrets within the etcd cluster.
What is the role of ConfigMap in Kubernetes
Essentially, a ConfigMap is a Kubernetes object used to store non-confidential data in key-value pairs. This data can be consumed by pods or other Kubernetes objects in your cluster. The primary role of ConfigMap is to separate configuration details from the container image, thus enhancing flexibility and reusability.
What is the difference between custom resource and ConfigMap : They store and retrieve structured data via dedicated API endpoints. Compared to generic solutions such as ConfigMaps, custom resources offer clearer intent, better separation of responsibilities, and an improved management experience when you're creating many instances of a particular data structure.
The limit for secrets is 1MB. I think 1MB is on the small side for what some people might want, and suggest we consider up to 5MB. The main questions are what the upper limit on a single piece of config data is and what granularity we want to quota total storage on. 1MB
The secret data on nodes is stored in tmpfs volumes. A per-secret size limit of 1MB exists.
What is the use of ConfigMap in Kubernetes
Kubernetes ConfigMap is a built-in Kubernetes API object that's designed to store your application's non-sensitive key-value config data. ConfigMaps allow you to keep config values separate from your code and container images. Values can be strings or Base64-encoded binary data.The ConfigMap applies globally, meaning that it affects every Ingress resource. In contrast, annotations always apply to their Ingress resource. Annotations allow overriding some ConfigMap keys. For example, the nginx.org/proxy-connect-timeout annotations overrides the proxy-connect-timeout ConfigMap key.ConfigMaps are a Kubernetes mechanism that let you inject configuration data into application pods. The ConfigMap concept allow you to decouple configuration artifacts from image content to keep containerized applications portable. If, for whatever reason, you enabled both configmaps and secrets, and there is a common property between them, the value from the ConfigMap will have a higher precedence. That is: it will override whatever values are found in secrets.
Should I set limits on Kubernetes : To maximize the efficient utilization of your Kubernetes cluster, it is critical to set resource limits and requests correctly. Setting your limits too low on an application will cause problems. For example, if your memory limits are too low, Kubernetes is bound to kill your application for violating its limits.
Is it safe to use Kubernetes secrets : Kubernetes Secrets are used to store sensitive information such as passwords, tokens, and certificates in a secure way. Secrets can be used by Kubernetes deployments, pods, and other resources that require this sensitive data. We all need someone to keep our secrets safe, in this case, it's in Kubernetes!
